PURCHASE and QUALITY ASSURANCE TESTING of CRUSHER GAUGES: TYPES M11, T17, & T19

1. Background. The Government has a long history of testing weapon systems. The measurement of peak pressure inside of a large caliber cannon or mortar tube is extremely important to verify the safety and soundness of the tube. To measure this pressure, the Army along with NATO has developed precision mechanical gauges and a standard method to accomplish this task. The US Army stock is getting low and needs to be replenished to continue to perform this critical mission. There are three types of gauges that need to be procured; Type M11 High Pressure Gauge, Type T17 Low Pressure Gauge, and Type T19 Mid Pressure Gauge.
